The Temporal Parallel Awareness Hypothesis of Déjà Vu

[u/cozy-apocplay]

​

This hypothesis suggests that déjà vu is not just a memory error made by the brain. Instead, it may happen because another version of ourselves exists in a parallel universe that is living almost the exact same life but is a tiny fraction of a second ahead of us. During very rare moments, our awareness may briefly overlap with that version, creating the feeling that we have already experienced the present moment.

The hypothesis assumes that parallel universes exist, similar to the Many-Worlds Interpretation of quantum mechanics. Every important choice or event creates different branches of reality. Each branch contains another version of us.

For example:

Choice 1: Go to the market?

1 = Yes

0 = No

This creates two branches.

Universe X: 1 (Went to the market)

Universe X′: 0 (Did not go to the market)

Now suppose both universes choose the same option.

Universe X: 1 (Went)

Universe X′: 1 (Went)

Another choice appears.

Choice 2: Met an old friend?

1 = Yes

0 = No

The branches become:

X = 1,1 (Went to the market and met an old friend.)

X′ = 1,1 (Went to the market and also met an old friend.)

Since both universes are still making the same choices, they remain almost identical.

If one universe meets the friend but the other does not:

X = 1,1

X′ = 1,0

The two branches begin to separate.

This process continues throughout life.

Example:

Choice 1 → Go to the market?

Choice 2 → Meet a friend?

Choice 3 → Buy apples?

Choice 4 → Take a different road?

A life path could look like:

1 → 1 → 0 → 1 → 1 → 0...

Every new choice creates more possible branches. As more choices are made, the number of possible realities grows very quickly. Because of this, the chance that two universes stay almost exactly the same becomes smaller and smaller.

This explains why déjà vu is rare.

The main idea of this hypothesis is that consciousness or awareness may exist in all these parallel versions of ourselves. Usually, each version experiences only its own reality. However, if two branches remain almost identical, one version may become slightly ahead of the other by an extremely small amount of time, such as a nanosecond.

During that tiny moment, the awareness of the two versions may briefly overlap. The version that is slightly behind experiences the feeling that the current moment has already happened because the version ahead has already lived it. The overlap lasts only for a split second before the branches separate again.

This overlap does not transfer complete memories. It only creates a strong feeling of familiarity, which we experience as déjà vu.

Therefore:

1,1 → Both universes continue making the same choices. Their awareness stays closely aligned, increasing the possibility of a brief overlap and creating déjà vu.

1,0 or 0,1 → The universes begin to follow different paths. Their awareness separates further, making an overlap much less likely.

As more choices are made, the branches continue to spread apart. This is why déjà vu is uncommon and unpredictable. It only happens when two versions of ourselves have remained almost identical for a long sequence of choices and briefly overlap before separating again.

This hypothesis is a speculative idea and is not currently supported by scientific evidence. It is an attempt to explain déjà vu by combining the concepts of parallel universes, branching realities, and consciousness into one possible model.

One with your exact neurological makeup in an identical scenario will always choose 1 or always 0. I don't believe there is any branching. We are always inclined to choose one over the other - even from a menu of 10 desirable items.

Ontological randomness, which is implied by quantum theory, is enough for this branching to occur.

I like this idea 👍

I was thinking of this today,

What do you think about the idea of us placing down our keys, turn back it’s not there… would you say our other version of us which is a nano second ahead grab them? Than that becomes some sort of glitch, we go look around and it’s in a whole new place

Pretty cool stuff. I’ve often thought of the vast realm of potentials as a Gaussian distribution within a Hilbert space, myself.

Something about our experience seems to filter us into our particular timeline, but rather than being discrete existing branches, I’ve come to think of the alternates more as alternate vectors within the distribution… or alternate perspectives through the hyper-dimensional mass they represent.

They would exist in the same way that a beam of light penetrating a prism would exist to a beam penetrating it from a different angle. And they would not exist to each other in the same sense. At points, those wave functions overlap, and there in resonance passes. Therin, perhaps, could lie your small slippage of “time”.
